Detailed Description

In the scenario that a plurality of terminals move across cells, in order to efficiently allocate dedicated terminal identifiers in a Cell, dynamic identifiers in the Cell are adopted as terminal identifiers, including a Cell radio network temporary identifier (C-RNTI, cell-Radio Network Temporary Identifier) and a deactivated state radio network temporary identifier (I-RNTI, active-Radio Network Temporary Identifier). The C-RNTI is allocated to the terminal in the connection state and is used for decoding the PDCCH scrambled by the C-RNTI in the search space, and after the terminal leaves the connection state, the C-RNTI is released, and the network side can continuously allocate the C-RNTI to other terminals. The I-RNTI consists of a base station identity (gNB ID) and a terminal identity (UE ID) valid within one radio access network (RAN, radio Access network) area.

In recent years, new terminals (also referred to as new communication units) such as a reader-writer or a repeater configured in the internet of things have been presented, and such terminals have the characteristics of fixed positions, no departure from a cell, or continuous communication requirements, etc., and the adoption of dynamic identification can cause excessive consumption of energy and signaling by such terminals.

Based on the above, in embodiments of the present application, a first cell of a first network device sends first configuration information to a first terminal; the first configuration information includes a first terminal identifier, and is used for the first terminal to communicate by using the first terminal identifier when the first terminal is located in a valid range corresponding to the first terminal identifier, and/or when a serving cell of the first terminal is the first cell. Based on the above scheme, when the terminal is located in the effective range corresponding to the first terminal identifier and/or the serving cell is the cell for transmitting the first terminal identifier, the reader-writer or the repeater and other novel terminals with fixed positions and no departure from the cell or continuous communication requirements can always use the first terminal identifier for communication, so that excessive energy and signaling consumption caused by using the dynamic identifier for communication are avoided.

The present application is described in further detail below with reference to the accompanying drawings and examples.

The embodiment of the application provides a cell access method, which is applied to a first terminal, wherein the first terminal is a novel terminal or a novel communication unit with the characteristics of fixed position, no departure from a cell or continuous communication requirement, and the like, such as a repeater, a reader-writer in the Internet of things, a communication relay, and the like. The communication between the terminal and the network device is frequent, so that it is considered that the protocol stack of the control plane and the user plane needs to be kept for a long time between the network device and the first terminal, and a relatively fixed static identifier is kept. Referring to fig. 1, the method includes:

step 101: first configuration information sent by a first cell of a first network device is received.

Here, the first configuration information may be issued through an RRC reconfiguration message, an RRC release message, an RRC connection setup message, an RRC connection reestablishment message, or other RRC messages. The first configuration information is sent by a first cell of the first network device, and when the serving cell of the first terminal is the first cell and/or the first terminal is located in a valid range corresponding to the first terminal identifier, the first terminal uses the first terminal identifier to communicate.

The first terminal identity may also be referred to herein as a fixed identity or a static identity. In practical application, the first terminal identifier may adopt a bit length of 16 bits, which is the same as the bit length of the C-RNTI, but is different from the C-RNTI in that the C-RNTI is only valid in the cell, and the C-RNTI is released after the terminal leaves the connection state, and the network side may assign the C-RNTI to other terminals, and the first terminal identifier may be understood as a dedicated identifier of the first cell and is a long-term valid identifier of the first terminal communicating in the first cell. In addition, unlike the I-RNTI, the first terminal identity is an identity that is valid for a long period of time within a network device that, once configured for the first terminal, reserves the first terminal identity for the first terminal for a long period of time and does not reassign the first terminal identity to other terminals.

Here, the first network device may be understood as a base station, e.g. a next generation base station (gNB, the next Generation Node B).

Wherein the effective range comprises an effective cell and/or an effective tracking area;

Furthermore, in an embodiment, the valid range corresponding to the first terminal identifier includes the first cell by default. Thus, when the first terminal is located within the first cell, the first terminal communicates using the first terminal identity.

In an embodiment, before the receiving the first configuration information sent by the first cell of the first network device, the method further comprises:

and reporting the capability information of the first terminal to the first network equipment.

Wherein the reported capability information includes at least one of:

the first information is used for indicating that the first terminal is a device type supporting communication by using the first terminal identifier, for example, indicating that the first terminal is a repeater, an internet of things terminal or a communication relay in the internet of things;

Thus, based on the capability information reported by the first terminal, the first network device can learn that the first terminal supports the allocation of the first terminal identifier, and can configure the first terminal identifier for the first terminal.

After the first network device configures the first terminal identifier for the first terminal, when the first terminal initiates a random access procedure, the corresponding random access procedure is as follows:

first, a first terminal sends a random access preamble MSG1, and then receives a random access response MSG2 about MSG1 from a network side, wherein MSG2 carries a temporary C-RNTI allocated by the network side. Then, the first terminal uses the first terminal identity instead of the temporary C-RNTI in the MSG3 or MSGA or RRC connection setup request message or RRC connection recovery message.

In addition, in the random access procedure described above, MSG3 may be scrambled using the TC-RNTI.

Next, the first terminal performs a downlink communication expansion description based on the first terminal identifier.

In an embodiment, after the receiving the first configuration information sent by the first cell of the first network device, the method further comprises:

receiving a first paging message sent by the first network device; the first paging message carries a first paging identifier; the first paging identifier comprises TMSI or the first terminal identifier;

Here, before receiving the first paging message, the first terminal is in an idle state (idle) or an inactive state (inactive) and communicates according to the identification type of the first paging identification carried in the first paging message. If the first paging identity is the same as or related to the first terminal identity, the first terminal does not need to initiate random access, i.e. does not need to enter a connected state, but directly receives the PDCCH.

Here, the first paging identifier is related to the first terminal identifier, which means that the identifier carried by the paging is partially the same as the first terminal identifier. For example, the page carries an identity of "123" and the first terminal identity is "123456". Thus, only a part of the first terminal identifier is sent, so that the number of paging bits is saved while the terminal is instructed to continue to use the first terminal identifier for communication. Alternatively, the first paging identifier is associated with the first terminal identifier, which may also mean that the identifier carried by the page is part of the first terminal identifier. For example, the paging carried identifier is "987654" and the first terminal identifier is "987", so that the terminal identifiers of a plurality of terminals can be connected in series in the paging message, and the terminal can find the part matched with the terminal identifier of the terminal from the paging carried identifier.

Specifically, the communicating using the first terminal identifier includes:

and descrambling the first PDCCH based on the first terminal identification.

Here, the first network device uses the first terminal identifier to scramble the first PDCCH, and after receiving the first PDCCH, the first terminal uses the first terminal identifier to descramble, obtain scheduling information in the PDCCH, and receive data information in the PDSCH according to the scheduling information in the PDCCH. In the related art, after receiving the paging message, the terminal needs to initiate random access to acquire the TMSI and the TA, and then the TMSI can be used for decoding the PDCCH.

If the first paging identity is a TMSI, e.g. a 5G-s-TMSI, in an embodiment the method further comprises:

and releasing or deleting the first terminal identifier.

Specifically, if the first paging identifier is a TMSI, the first terminal needs to initiate a random access procedure, the first terminal identifier is not used, and the first terminal releases or deletes the first terminal identifier.

In practical application, the TMSI is usually carried in the first paging message without configuring the first terminal with the first terminal identifier. It may also be understood that if the first paging message does not carry the first terminal identifier, it is indicated that the first cell that sends the first paging message does not have the corresponding first terminal identifier. If the first network equipment configures the first terminal identifier for the first terminal, paging is performed by using the first terminal identifier preferentially, if the response of the first terminal about the first paging message is not received, the first network equipment indicates that the first terminal has left a first cell corresponding to the first terminal identifier, and the first network equipment uses the TMSI to perform paging in a larger range. Therefore, when the first terminal finds that the TMSI is used in the first paging message for paging, the first terminal can release or delete the first terminal identifier, which indicates that the network side has no available first terminal identifier.

In an embodiment, the first paging message further carries at least one second cell identifier, which is used for indicating the first terminal to use the first terminal identifier to communicate in a cell corresponding to the at least one second cell identifier.

Here, if the first paging message carries a second cell identifier, the first terminal directly decodes a search space of a cell corresponding to the second cell identifier by the first terminal identifier; if the first paging message carries at least two second cell identifiers, the first terminal considers that the cell areas corresponding to the second cell identifiers form carrier aggregation, and at the moment, the first terminal uses the first terminal identifier to decode the search space of the cell areas of the carrier aggregation.

In an embodiment, the method further comprises:

and receiving third configuration information sent by the first network equipment.

The third configuration information is used for indicating a cell corresponding to the at least one second cell identifier.

Here, the third configuration information may be sent to the first terminal through an RRC release message or an RRC reconfiguration message, and is used to configure a secondary cell related to the first terminal identifier, where the secondary cell is used for a secondary cell of carrier aggregation when the first terminal uses the first terminal identifier to perform communication, that is, the second cell above.

In the related art, the secondary cell of carrier aggregation configured by dedicated signaling in the connected state is immediately effective, and in this scheme, the second cell indicated in the third configuration information is effective when the first terminal accesses the network using the first terminal identifier next time, so as to quickly use carrier aggregation when the first terminal establishes a connection.

Next, the first terminal performs an uplink communication expansion description based on the first terminal identifier.

In an embodiment, the method further comprises:

In practical application, because the position of the first terminal is fixed and the variation of the TA is very small, the first terminal always defaults to use the configured first TA for communication, and the first terminal stores the first TA and then applies the first TA to the subsequent uplink communication process.

When the first terminal has uplink data to send, as an implementation manner, in an embodiment, the method further includes:

judging whether the current service cell of the first terminal is positioned in the effective range corresponding to the first terminal identifier or not, and obtaining a judging result;

and when the judging result represents that the current service cell of the first terminal is located in the effective range corresponding to the first terminal identifier, transmitting uplink data by using the first terminal identifier.

Specifically, the first terminal may determine whether the cell identifier of the current serving cell is the same as the first cell identifier, or whether the tracking area of the current serving cell is within a valid range corresponding to the first terminal identifier, according to the cell identifier of the current serving cell, for example, a physical cell identifier (PCI, physical Cell Identity) and/or a global cell identifier (NCGI, NR Cell Global Identifier) in the NR network. The first cell identifier may be a first terminal identifier, or may be a cell identifier obtained when the first terminal receives the first terminal identifier, or may be a cell group identifier obtained when the first terminal receives the first terminal identifier, where the corresponding first cells are the same, or it is determined whether the current serving cell is a cell that sends the first terminal identifier to the first terminal.

When the judging result indicates that the current service cell of the first terminal is located in the effective range corresponding to the first terminal identifier, the first terminal uses the first terminal identifier to transmit uplink data. Specifically, in an embodiment, the transmitting uplink data using the first terminal identifier includes:

That is, if the network side configures CG resources for the first terminal, the first catapulting may use the CG resources to send uplink data using the first TA in the active time. Or based on dynamic scheduling, the first terminal sends a scheduling request to the network side by using the TA of the last communication, so as to receive uplink scheduling information sent by the network side, and transmit uplink data.

And when the judging result shows that the current service cell of the first terminal is not positioned in the effective range corresponding to the first terminal identifier, the first terminal releases or deletes the first terminal identifier, and a new terminal identifier of the current service cell is used for communication.

When the first terminal has uplink data to send, as another implementation manner, in an embodiment, the method further includes:

Here, the network side instructs the first terminal to use the first terminal identifier for uplink transmission, and the network side also instructs a primary cell (PCell) and a secondary cell (SCell) of carrier aggregation that can be used when the first terminal performs uplink transmission, and optionally, the network side may also instruct CG of the primary cell and the secondary cell. In this way, when the first terminal has uplink data to be transmitted, the uplink data is directly transmitted on the CG of the primary cell and the secondary cell.

Correspondingly, the embodiment of the application also provides a cell access method, which is applied to the first network device, as shown in fig. 2, and includes:

step 201: and sending the first configuration information to the first terminal.

The first configuration information includes a first terminal identifier, and is used for the first terminal to communicate when the first terminal is located in a valid range corresponding to the first terminal identifier and/or when a serving cell of the first terminal is a first cell; the first cell characterizes a cell from which the first configuration information is sent.

the reported capability information includes at least one of:

In the above scheme, the method further comprises:

transmitting third configuration information to the first terminal; wherein,

In the above scheme, the method further comprises:

sending fourth configuration information to the first terminal; wherein,

In the above scheme, the method further comprises:

In the embodiment of the application, a first cell of a first network device sends first configuration information to a first terminal; the first configuration information includes a first terminal identifier, and is used for the first terminal to communicate by using the first terminal identifier when the first terminal is located in a valid range corresponding to the first terminal identifier, and/or when a serving cell of the first terminal is the first cell. Based on the above scheme, when the terminal is located in the effective range corresponding to the first terminal identifier and/or the serving cell is the cell for transmitting the first terminal identifier, the reader-writer or the repeater and other novel terminals with fixed positions and no departure from the cell or continuous communication requirements can always use the first terminal identifier for communication, so that excessive energy and signaling consumption caused by using the dynamic identifier for communication are avoided.

In addition, since the number of dynamic identifiers in one cell, such as the number of C-RNTI is limited, the number of C-RNTI limits the number of terminals which can be accommodated in the cell, and in the scheme of the application, the terminal does not need to use a new C-RNTI, and the first terminal identifier can be always used in the communication in the cell, so that the consumption of the dynamic identifiers in the cell is saved. And moreover, the first terminal identifier which can be used for a long time is adopted, the network equipment can store the context and the terminal capability of the terminal using the first terminal identifier for a long time, and the context and the terminal capability of the terminal do not need to be repeatedly acquired from the core network, so that the terminal can be quickly awakened, and the access time delay of the terminal is shortened. Meanwhile, as the terminal does not need to carry out a random access process, the pressure of competing random access is relieved, the terminal can directly use the first terminal identifier to carry out uplink and downlink transmission, and the terminal identifier does not need to be acquired again through a random access message.
